9 Claims. (01. 57-425) This invention relates to a traveler for spinning rings and more especially to the type known as spinning travelers. The invention may also be employed in twister travelers as some twisters use a type of traveler running on a horizontal flange at the top of the ring.

It is an object of this invention to provide a traveler which is self-ventilating and which has vanes thereon for directing air to the inside of the traveler to thereby blow grit, dust and other foreign matter from the ring and traveler and prevent its lodgement thereon. It is a well known fact that cotton especially has a certain amount of grit and abrasive substances thereon which are removed from the yarn as it passes through the traveler on the way to a bobbin in a spinning or twisting operation. By providing a traveler having vanes and slots associated therewith, the air is directed from the outside tofthe inside of the traveler due to the travel of the traveler on the ring, thereby blowing lint, grit and the like from the traveler, but also from the ring on which it travels.

It is another object of this invention to provide a ring traveler having louvres or ventilating spaces therethrough which serve not only to remove grit, lint and the like from the traveler and the ring on which it travels, but also serves to cool the traveler. Furthermore the slotted construction enables the traveler to be made of harder material, and thus being more easily bent in the forming operation for making new travelers, thereby giving the travel much increased life. This also will definitely increase the life of the ring on which the traveler operates.

It is another object of this invention to provide a traveler having louvres and slots therein which serve to ventilate the space between the traveler and the ring on which it travels, said slots also serving to lift one side of the traveler and de-' press the other side.

It isa well known fact that the inner leg of the traveler of the type shown is pulled upwardly to a greater extent than the outer leg and occupies a running position substantially as shown in Figure 2. This causes much faster wear between the inner horn of the traveler and the lower inner edge of the flange than between the outer horn of the traveler and its associated flange. By providing louvres of the type shown, and especially of the type shown in Figures to inclusive, the forwardly disposed louvre on the outside leg of the traveler, tends to raise the outer leg of the traveler due to air being forced downwardly through the outer slot; Whereas the rearwardly projecting vane or louvre on the inside leg of the traveler tends to force the inside leg of the traveler downwardly and thus effects a leveling operation for the traveler. This leveling operation more equally distributesthe wear on the two horns of the travelerwhich engage the lower flange and surfaces and the vertical sidewalls of the ring. This gives longer life to the traveler and also the ring on which it operates.

Some of the objects of the invention having been stated,-other objects will appear as the description proceeds, when taken in connection with the accompanying drawing, in which- Figure 1 is a plan view of a portion of a ring rail showing a ring having one form of my improved traveler mounted thereon;

Referring more specifically to the drawing, the numeral 10 indicates a ring rail for a spinning or twister frame, in which a-plurality of rings H are mounted, there being only one ring shown in the drawing. In the center of the ring 1 I, there is rotatably mounted a bobbin or other yarn holder IZ-onto which yarn I4 is wound during a twisting or spinning operation. This yarn passes through a traveler I5 as shown in Figures 1 and 2 on its way from the source of supply to the bobbin or yarn holder l2.

In Figures 3 and 4, the traveler I5 is shown as having an arch or body portion l6 and horns l1 and I8. This is the conventional ring traveler, except that it has slots such as l9 and 20 formed therein by a suitable punching operation. The material which is punched from the slots [9 and 20 is bent upwardly to form vanes 2| and 22.

As this type of traveler moves around the ring, the air is forced in through the forward slot [9 or 2|, depending upon the direction of movement of the traveler, and is directed downwardly through the slot I9 to not only cool the traveler, but also to lift it upwardly. This structure serves to permit the traveler to be made of harder material, and therefore bent more easily. This traveler has the slots [9 and 20 so that regardless of which way the traveler is snapped onto the ring, a forwardly and upwardly directed vane 2| or 22 will be disposed above its associated slot.

In Figures 5, 6 and '7, another type of traveler 23 is shown which is provided with a forwardly and upwardly directed vane 24, said vane having associated therewith, a slot 25. This traveler also has a rearwardly and upwardly directed vane 26 with an associated slot 21. It will be noted that vanes 24 and 26 are staggered relative to the longitudinal center line of the traveler, that is the vane 24 engages one swath of air and the vane 26 engages another parallel swath as the traveler moves longitudinally along the ring. When this traveler is placed in position on a ring, and is moving in a direction toward the observer in Figure 5, the air will be forced downwardly through slot 21 by vane 28 to raise the outer half of the traveler; whereas the vane 24 having the air strike against the upper side thereof will have a tendency to depress the inner half of the traveler, and .relieve some of the pressure on the lower inner surface of the upper horizontal flange disposed on top of the ring.

In Figures 8, 9 and 10, a slightly modified form of traveler 28 is shown, this form being similar to the structure of Figures 5,. 6 and 7 except that the slots 29 and 30 with their associated vanes 3| and 32, respectively, are substantially longer than in Figures 5, 6 and '7 and extend throughout the arch or body portion of the traveler and down onto the sideleg portions if desired. The action of the traveler 28 will be similar to traveler 23, except that a greater volume of air will be collected by the vanes.

In Figures 11, 12 and 13, a slightly modified form of traveler 33 is shown in which slots 34 and 35 extend throughout the arch or body portion and down onto the vertical leg portions of the traveler. The intermediate portion of the arch or body portion, designated by reference character 36 is formed into the arc of a circle when viewed in cross section, thus providing two upwardly directed elongated vanes 31 and 38. Likewise, these elongated vanes are preferably staggered relative to the longitudinal center line of the traveler. A traveler of this type can be very easily bent and can be made out of much harder material than if it were a solid blank. as suitable forming dies can be employed for bending the blank into the shape of the traveler so as to exert the proper pressure on the various portions of the traveler after the blank has been stamped and slotted, and the vanes formed ready for the final forming. operation.

In a. type such as shown in Figures 8, 9 and 10, the forwardly and upwardly directed vane 3| assuming the traveler is moving on the ring in a direction which is downwardly on the drawing, will collect the air and force it downwardly through slot 29 and cause the outer half of the traveler tobe raised upwardly; whereas air striking against the upwardly and rearwardly extending vane 32 will force the inner half of the traveler downwardly and relieve some of the pressure on the lower inner surface of the horizontal flange of the ring.

In the form shown in Figures 11, 12, and 13, the balancing effect of the forms as shown in Figures 5 and 10 inclusive will not be present to such an extent as in Figures 5 to 10 inclusive, but the vanes 31 and 38 extending throughout the body or arch portion of the traveler and down onto the vertical leg portions, if desired, will collect the greatest amount of air, will keep the traveler perfectly cool, will cause a greater amount of air to be blown on the ring to remove foreign substances therefrom. Also the traveler can be much more easily bent than in the other forms, thus enabling the manufacturer to use a very much harder grade of material and one which will wear much longer than if it were made of a solid blank,

In the drawing and specification, there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being set forth in the following claims.
